Does anyone have some good hints for the 2.8 cage tool? I got it to do what I wanted once, then after that I could not. It didn't break gimp, I just can't really figure out how to get it to change the shape of my selection.

Hi 2-ton. The cage tool is still a big mystery to me too.

BUT!

The trick is to get the nodes around the image how you want them first.
Then once you have them all connected you can select around 2 or more to move 2 or more at once, or you can move one at a time. The nodes that change to squares are the ones that will move together.

I do not use it much.

what is weird is that the first time I tried it, it worked great, but then after that it wouldn't work again, it didn't make any changes. I'll just play with it some more, and see if I am missing something obvious!

Make sure you are using it on the right layer and select enter when you are ready to commit the transform change.
Also make sure your cage nodes are way outside your image area or it will tear it in places.

So is the sequence to make the cage, hit enter, then move the points where you want the selected image to change shape? Or do you make the cage, then move the nodes, and then click enter? If so, then shouldn't the image morph as you pull the nodes?

To be honest, the cage tool has been a disappointment to me. It never works the way I want or expect it to. The old Paint shop Pro was lousy but had a really good cage tool. I was hoping the Gimp version would be as good, maybe over time they'll get it fine tuned.

I agree with this. I suspect that most users expect the cage tool just to push the image around, lots of times it just breaks it.

A comparison between a 5 MB java application ( limited but good for netbooks) which works and Gimp.


Has me puzzled.

You would want to create the cage first, then move your nodes around to transform the image, and lastly select enter or return on your keyboard 2-ton.

Likewise. I would love Gimp to have a tool like PS where you draw a rectangular selection and warp the grid.
